The substance do biochemists often search for in fossils to help better understand the evolutionary relationships of the organism that formed the fossil - A. DNA
DNAis the genetic material that is found in every living organism that provides genetic information.
It also provides evidence of evolution.DNA sequences vary from species to species, but there are many overlapsThe ongoing branching of the sequencing produces multiple lines of descent.It can be inferred by comparing the DNA sequences of different organisms to check or find the evolutionary relationships of the organism that formed the fossilThus, The substance do biochemists often search for in fossils to help better understand the evolutionary relationships of the organism that formed the fossil - A.

Carbon monoxide (CO) is an odorless, colorless, and tasteless gas that is toxic in high enough concentrations. It can be a by-product of burning fossil fuels. CO binds irreversibly to the protein (hemoglobin) that transports O2 throughout your bloodstream. As you are exposed to high amounts of CO over a period of time your available hemoglobin becomes unable to bind to O2 because it is bound to CO. In your own words, explain what would happen to cellular respiration and what overall effect this would have on the organism.
Answer:
Carbon monoxide has much more affinity for the hemoglobin than the affinity of the oxygen to the hemoglobin almost 300 times more, which allows the Hb to bind with carbon monoxide irreversibly. Due to this, the small quantity of CO can also reduce the ability of oxygen transport of the hemoglobin.
Longer exposure of CO to the cHb will lead to reducing oxygen release by the Hb that is bound to oxygen in this T state which causes less oxygen availability. In aerobic oxidation mechanisms like oxidative phosphorylation will eventually stop. It will be shifted to anaerobic cellular respiration. The net production of ATP drastically reduced due to anaerobic glycolysis. Cells will eventually start to die causing the death of an organism.

Q. Why is energy required by an organism even during sleep ?
Q. Give the energy transformation that takes place in the process of photosynthesis.
Q. What is chlorophyll ?
Q. Name the various factor which affect the rate of photosynthesis.
Q. Define photolysis.
➥ Even, when an organism is asleep, various biological processes keep on occurring in its body which requires energy.
➥ During photosynthesis‚ “Solar energy is converted into chemical energy”.
➥ “Chlorophyll” is a green coloured pigment found in plants that helps in absorbing sunlight used in photosynthesis.
➥ Several factors which affect the rate of photosynthesis:
Light. Temperature. Water.CO2.➥ “Photolysis” is the process by which water is split into oxygen, which is released into the atmosphere, and hydrogen.
A marathon runner is running a race. During the race the marathon runners heart rate and breathing increases. Which of the following explains why the marathon runners' body is responding in this way?
Answer:
Warmer temperatures increase your heart rate. In addition to pumping more blood to the muscles, your heart also transports more blood to the skin in order to cool it. Increased demand causes your heart to beat faster -- anywhere from 20 to 40 beats per minute higher than normal.

Please it’s worth 40 points I promise I will follow you and mark brainleist. Explain how a mouse uses its senses to act when it is in danger. Describe how the mouse heart and lungs work together when it smells a predator. Explain how the model can show what happens to the mouths breathing when it smells a predator this is a test please help
When the twitching pink nose of a mouse detects danger, the animal has to act fast. Fortunately, a predator rapidly triggers the release of stress hormones in the mouse and prompts behaviors that reduce the risk of it becoming the predator’s latest snack. helping explain how the brain translates danger signals detected by the nose into a physiological response. The research offers clues to the larger puzzle of how animals, including humans, perceive and respond to fear.

question 2.

True
False

Question 3.
Animals and plants rely on each other in a process called the carbon cycle.
True
False
Answer:
All true (sorry if I'm wrong )
Answer:
Question 1: True
Question 2: False
Question 3: True
Explanation:
Question 1: Organism's use and consume energy (work energy) every single day to get through what they need to do.
Question 2: Green plant's using energy from sunlight is refered to as photosynthesis not respiration. Respiration is the need to get rid of carbon dioxide gas aka breathing.
Question 3: Carbon cycle is the process where carbon compounds are interchanged among the biosphere, geosphere, pedosphere, hydrosphere, and atmosphere of the earth.
1. Carbon & sunlight present in the atmosphere is absorbed by plants for photosynthesis.
2. These plants are then consumed by animals and carbon gets bioaccumulated into their bodies.
3. These animals and plants eventually die, and upon decomposing, carbon is released back into the atmosphere.
4. Some of the carbon that is not released back into the atmosphere eventually become fossil fuels.
5. These fossil fuels are then used for man-made activities, which pumps more carbon back into the atmosphere.
You see the relationship here? So yes, Animals and plants rely on eachother in the process refered to as the carbon cycle.
